Embodiment Construction

[0029] The flow of a method for determining the forwarding state of an end-to-end pseudowire simulation node in the present invention is as follows: figure 1 shown, including the following steps:

[0030] Step s101, determining the local state of the node. Among them, the state of the local end is determined by the connection circuit of the node and the state of the local tunnel, that is, when the connection circuit is UP (existing) and the local tunnel is UP (existing), the local state of the node is forwardable; When one of the connection circuit or the local tunnel of the node does not exist, the local state of the node is non-forwarding.

[0031] Step s102, obtaining the remote state of the node. The remote state is transmitted through the MAPPING / NOTIFICATION message extended by the LDP signaling.

[0032] Step s103, determining the forwarding state of the node according to the local state and the remote state of the node. When the local state of the node is forwardab...

Abstract

This invention provides a method for determining the transmission state of simulation nodes of end to end false lines including: determining the state of the local end of a node and getting the far end state of said node to decide the transmission state of the node, which can decide the transmission state of a node accurately and simply by the local state of the node and the far end state of the node connected with it and realizes the consistent transmission state of all nodes in false lines, namely and the state of the whole communication links can be understood by one node.

Description

technical field [0001] The invention relates to simulation technology in the communication field, in particular to a method for determining the forwarding state of an end-to-end pseudowire simulation node. Background technique [0002] Telecom operators initially provided customers with Layer 2 links in the form of Leased Lines. However, due to the disadvantages of long construction time, inability to share lines, high prices, and difficult management, this method is not suitable for those with many branches and fast growth. Therefore, with the development of ATM (Asynchronous Transport Mode, Asynchronous Transfer Mode) and FR (Frame Relay, Frame Relay) technology, telecom operators began to use VC (Virtual Circuit, virtual circuit) to provide customers with point-to-point two Layer links, on which customers build their own three-layer network to carry data streams such as IP (Internet Protocol, Internet Protocol), IPX (Internet Packet Exchange, Internet Data Packet Exchange...
